There could be a good "death tour" in Collinsport also. Imagine the tour guide pointing out where past and present residents of Collinsport met their deaths in The Collinsport Inn, The Blue Whale, the docks along the harbor, the site where the Todd's antique shop burned down, etc.
Of course, the Collinwood estate, where most of the murders took place, would be strictly off-limits to any sightseers, unfortunately.
